Application filed March 21, 1918. Serial No. 223,828.

To ((ZZ whole it may concern:

Be it known that I, CLAUDE U. TYnRELL, a citizen of the United States, and resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bubble-Blowers, of which the following is a full, clear, and exact specification. I

This invention relates to improvements in bubble blowers, in which heretofore the blow pipe projects transversely through the container for the soap water, terminating at its outwardly projecting end in a flaring cup, or funnel, provided with an aperture either internally or externally of the container.

' The prime object of my invention broadly stated is to provide the container with a concaved bottom, integrally formed there with, the apex of which bottom is provided with an aperture surrounded by a blow pipe tightly fitting against said bottom and projecting along a line extending axially through the container from top to bottom, and provided externally of the container with a perforation, located substantially near the top of the container, and bent to such a form that when operating the bubble blower the container is suspended in a vertical line therefrom.

A further object of my invention is to have the blow pipe provided with an adjustable valve located outwardly from the top of the container for varying the force of the air supplied to the film of soapy water.

\Vith these ends in view, my invention finds embodiment in certain features of novelty in the construction, combination, and arrangement of parts of which said objects and certain other objects are attained, all as hereinafter fully described, with reference to the accompanying drawings and more fully pointed out in the claims.

In said drawings:

Figure 1 illustrates in perspective, with parts broken away, a bubble blower in which my invention finds its embodiment.

Fig. 2 is a vertical section thereof.

Fig. 3 is a bottom plan View of the bubble blower, with its several parts indicated by dotted line;

Fig. 4 is an enlarged detail sectional View of the valve for regulatingthe pressure of air from the mouth of the operator, upon the soap water passing through the perforation in the blow pipe, deposited in the form of a film at the bottom thereof.

The container of the bubble blower of my invention consists of a top portion (3, and

bottom portion 7, preferably formed from stampcdout thinshect metal, connected by means of a water-tight locking joint 8, of the usual locking joint construction commonly employed for other two-part contain ers.

The top 6, of the container is provided with a suitable opening 9, for filling pur poses, closed by a stopper 1(), and projecting axially through the container from top to bottom is a blow pipe 11, provided with a perforation 12, located in one side wall, of, and toward the upper end of the container.

The inner end of the blow pipe 11, projects against and forms a tight joint with the bottom 13,.of the container, and has its outer end portion bent, as indicated at let, at an angle of about 45 to the axis of the con tainer so that when the mouth of the operator is applied to the free end 15, of the blow pipe, the container may be suspended in a vertical position.

It will now be observed that the bottom surface of the container projects inwardly, and is concave, as indicateiil at 16, by bending the metal of the bottom inwardly to the form of a hollow truncated, somewhat shallow cone, provided at its apex with a perforation 17, the edge of the surrounding walls, of which operates to support soap water conducted through the lateral perforation 12, in the blow pipe, and by capillary attraction prevent the discharge of the soap water until it is discharged by the pressure of the air projected through the pipe from the mouth of the operator.

In operation the container is filled with soap water, the level of which must be below the perforation 12, and preferably until the container is about half filled, following by plugging up the orifice with the stopper 10. and then shaking the container until sufficient soap water has passed through the perforation 12 in the pipe to form adeposit in the pipe covering the end surfaces of the Wall surrounding the perforation 17, for forming a bubble,'the depth of soap water thus deposited, and therefore the size of the bubble being determined by the violence. and length of time the container is shaken.

The size of opening through the bottom of the retainer is such that the soap Water is prevented by capillary attraction from discharging therethrough, until the deposited film is exposed to air pressure from the mouth of the operator of sufiicient force for overcoming this capillary attraction.

In this connection it will now be seen by reference to Fig. 2, that the concave surface of the bottom of the container sub stantially conforms to the spherical surface of any considerable size of bubble opposed to it, with the result that capillary attraction prevents the bubble from wabbling or separating from the spherical surface, until the container is gently but quickly vibrated laterally, and whereupon the bubble will be released, and be free to float intact through the air.

It not infrequently occurs that the operator in efforts to operate bubble blowers inz'tdvertel'itly expels the air from his mouth with a force bursting the bubble before it reaches its full size, if not in the first instance preventing its formation, and which I find may be prevented. by means of an ad just-able valve in the blow pipe, as for example as shown in l igsiiand l, wherein the blow pine ll, is provided with perforations l8, l8, diametrically opposite each other, and surrounded by a collar 19, provided with an opening through one side of which in register with said perforations is a screw threaded valve 20, a thumb piece 21, and an inner end face 22, having the form of a cone, opposed to a corresponding depression 23, in the collar 19. With the valve thus constructed it is. adapted for adj ustably contracting the passage through the blow pipe and forming therein an angular passage between the end of the valve, and the opposing depression in the collar, as indicated in 3 and -i deflecting the air currents in their passage through the pipe.

With the iiiward movement of the valve toward its s mt the passage in the blow pipe wiii be correspondiugly reduced, as will be the force of the pressure of the air from the mouth of the operator, to and upon the soap water deposit at the bottom of the pipe.

The employment of such a valve is desirable, especially with a bubble blower, when used by chihlren, for the reason that they are very liable to blow so hard, as to prevent the formation and development of a bubble,

My invention, however, is not limited to the particular construction of the valve shown and described herein, but includes any form of a valve by which the passage in the blow pipe may be contrived for prod uc-- ing the results above described.

llaving described my invention what I claim and desire to secure by Letters Patent is 1. A bubble blower comprising in combination a container, provided with a perforation in the bottom thereof, a blow pipe projecting into andterminating against the surface of said bottom in register with a perforation in said bottom.

2. A. bubble blower comprising in combination a container, provided with a perforated bottom, a blow pipe projecting axially thei'e through, extending and terminating against the surface of said bottom, in register with said bottom perforations.

3. A. bubble blower comprising in combination a container, the bottom surface of which is'concave, and provided with perforations, and a blow pipe, projecting through the container, one end of which pipe opposes and is secured to the said bottom surfacein register with said perforations.

at. A bubble blower comprising in combination a container provided with an in wardly projecting cancavo-convcx bottom, provided with a perforation through the apex thereof, and a blow pipe projecting longitudinally through the container, surrounding the perforations in, and allixed to said bottom.

A bubble blower comprising in combination a container, the bottom of which projects inwardly to the form of a truncated hollow cone, a blow pipe projecting into and surrounding the longitudinal axis of the container and the open end portion of the truncated cone, and secured to the opposing surface of the cone.

In witness whereof I have hereunto set my hand and afl'ixed my seal this 18th day of March, A. D. 1918.
